Your vented crawl space could be to blame for your high utility bills

Fiberglass insulation installed in the crawl space ceiling will not protect you from frozen pipes, cold floors, and high heating bills. Ductwork in a vented crawl space is another problem. Outside air and temperatures make your ducts cold in the winter and hot during the summer. This forces your HVAC system to work overtime to deliver air at the proper temperature, cutting system efficiency by as much as 25-40 percent.

How we seal out the cold in your crawl space

Instead of worrying about your crawl space and making temporary repairs, let us permanently solve your cold weather problems. We don’t just winterize crawl space pipes or vents. Instead, we seal and winterize your entire crawl space foundation to bring your plumbing and heating system inside your home’s conditioned space. Here’s how our process works:

A complete system. Our patented CleanSpace® crawl space products are designed to work together, providing complete sealing, insulating & moisture control. This photo shows rigid foam wall insulation, drain pipe, drainage matting, floor insulation and a moisture barrier.

• Air seal & insulate the rim joist. A tremendous amount of heat is lost through the rim joist that rests on your crawl space foundation.We prevent frigid air from leaking in by sealing gaps around the perimeter of your foundation. Then we reduce conductive heat loss by insulating the rim joist with foam insulation.
• Insulate crawl space walls with rigid foam. We install high-performance SilverGlo™ rigid foam insulation against the crawl space walls. SilverGlo™ does what fiberglass can’t: it stops air leaks, never loses R-value, and can’t absorb or be damaged by moisture.
• Seal & insulate the crawl space floor. In colder climates, we recommend installing TerraBlock™ foam insulation on the crawl space floor. This specialized flexible insulation is then covered with our strong poly CleanSpace® moisture barrier that completes the sealing process. The crawl space is now isolated from outside conditions.

Let us prevent problems with your vented crawl space

Avoid condensation problems. Humidity in the crawl space can form condensation on cold surfaces, like ducts and pipes. This can lead to mold, rot & leaky ducts. Properly insulating & sealing the crawl space will solve these problems.

General contractors and home repair professionals can’t transform your crawl space like we can. We specialize in basement and crawl space repair. Our innovative products aren’t available to other contractors. Our system provides complete sealing, insulation and moisture control.

An extra bonus: Year-round benefits

The improvements we make to winterize your crawl space stay in place all year round, improving interior comfort and energy efficiency at all times of the year. And don’t forget another important benefit: Your crawl space will look as great as it performs.
